100% bonus depreciation is back, and rental property owners should be paying attention.
But there is one big mistake Anchorage landlords and investors should not make: 100% bonus depreciation does not automatically mean you get to write off the entire rental building.
That is where a lot of online tax content gets sloppy. People hear "100% bonus depreciation" and assume the whole property qualifies. In most rental real-estate situations, the building itself is still depreciated over a long recovery period. Residential rental buildings are generally depreciated over 27.5 years, and commercial buildings are generally depreciated over 39 years. The opportunity usually comes from identifying certain shorter-life assets that may qualify for faster depreciation.
That is where cost segregation comes in.
The IRS guidance cited in the supplied package says the OBBB provides a permanent 100% additional first-year depreciation deduction for qualified property acquired after January 19, 2025. IRS Publication 946 also explains that qualified property generally includes tangible property depreciated under MACRS with a recovery period of 20 years or less, along with certain other property categories.
For rental property owners, this matters because some components inside or around a property may have shorter recovery periods than the main building. A cost segregation review looks at whether parts of the property can be separated from the long-life building and depreciated faster when the facts support it.
That does not mean every rental needs a full study. It means every serious rental owner should understand the question.
Why this matters for Anchorage owners
A lot of Anchorage investors are not buying huge institutional apartment complexes. They are buying duplexes, fourplexes, small multifamily properties, single-family rentals, condos, and mixed-use properties. Many of these properties have updates, appliances, flooring, cabinets, lighting, site improvements, or other components that may deserve a closer look.
The tax opportunity depends on the facts, including:
- Property type
- Purchase price and land allocation
- Acquisition date
- Placed-in-service date
- Improvements made before or after the property became a rental
- Whether the property has enough shorter-life components to justify a deeper review
- Whether the owner can actually use the deductions
That last point matters. A large depreciation deduction does not automatically mean an immediate tax benefit. Rental losses may be limited by passive-activity rules, at-risk rules, basis rules, or the taxpayer's overall situation. The IRS says passive losses that exceed passive income are generally disallowed for the current year and carried forward.
So the real question is not just, "Can we create more depreciation?" The better question is: would accelerated depreciation actually help this owner based on their tax picture?
What 100% bonus depreciation could change
When bonus depreciation was phasing down, some cost-segregation results were less powerful than they were during the 100% bonus years. Now that 100% bonus depreciation is back for certain qualified property, the timing conversation changes again.
A cost segregation review may be worth exploring when:
- You bought a rental property after January 19, 2025.
- You placed a rental property in service after that date.
- You completed major improvements.
- You own a duplex, fourplex, small multifamily, or commercial property.
- You have enough income or passive income to make the deduction useful.
- You are doing year-end tax planning before the return is filed.
But this still needs to be handled responsibly. A cost segregation study should not be a random percentage pulled from the internet. The IRS has a Cost Segregation Audit Techniques Guide used to evaluate studies, and that alone should tell owners that documentation and classification matter.
## The mistake to avoid
The biggest mistake is assuming this is either "always amazing" or "only for huge properties." Both are wrong.
Some small properties may not justify a full study. Some small multifamily or condo-rental properties absolutely deserve a review. Some owners may generate a large paper loss but not be able to use it immediately. Other owners may be in a position where timing the deduction matters a lot.
This is why a screening conversation is usually the first step. Before paying for a full cost-segregation study, rental owners should review:
- Purchase settlement statement
- Property type
- Land/building allocation
- Improvement history
- Placed-in-service date
- Current depreciation schedule
- Income level and passive-loss position
- Holding-period plans
Bottom line
100% bonus depreciation being back is a big deal, but it is not a magic button.
For Anchorage rental property owners, the opportunity is not "write off the whole building." The opportunity is to identify whether part of the property may qualify for faster depreciation and whether that strategy actually helps based on the owner's full tax picture.
If you own a rental property in Anchorage, Eagle River, Wasilla, Palmer, or elsewhere in Alaska, this may be the right time to review your depreciation setup before another tax return gets filed on autopilot.
